High-capacity sorptive extraction is an innovative, labour-saving sampling approach to the analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) in liquids and solids by TD–GC–MS.
Extending the capability of thermal desorption (TD), Markes International's HiSorb™ high-capacity sorptive extraction probes and accessories are ideal for trace-level component characterisation, aroma profiling, quality control and advanced research across a wide range of applications. Full automation of HiSorb is now possible on Markes' Centri® platform.
WHY USE HIGH-CAPACITY SORPTIVE EXTRACTION?
Robust, easy-to-use probes allow unattended sample preparation and maximum productivity.
Simpler and quicker to use than solvent extraction.
Reduce costs associated with solvent consumption and disposal.
Re-usable probes and tubes minimise the cost per sample
.
Improved detection limits over SPME due to the larger capacity of the PDMS sorbent.
Cryogen-free pre-concentration by TD prior to automated GC–MS analysis improves sensitivity.
Flexible sampling (immersive or headspace) for both liquid and solid samples.
Compatible with industry-standard TD tubes on all leading commercial systems
APPLICATIONS
AROMA PROFILING OF PET FOOD USING HIGH-CAPACITY SORPTIVE EXTRACTION AND TD–GC×GC–TOF MS
This study demonstrates the use of high-capacity sorptive extraction, with analysis by TD–GC×GC–TOF MS, for the aroma profiling of meat-based cat food, including the reliable detection of trace off-odour components.
